boolean GNOME::Magnifier::ZoomRegion::setMagFactor | ( | in float | magX, | |
in float | magY | |||
) |
Set the current x and y magnification ratio.
(Convenience method for setting mag-factor-x and mag-factor-y properties). Note that if the zoom region's target hasn't yet been realized or mapped to the display, we will not be able to detect failure, so a return of TRUE must be taken on advisement if the operation is performed on a newly-created zoom region.
magX | the magnification factor in the x direction for the specified region. | |
magY | the magnification factor in the x direction for the specified region. |
void GNOME::Magnifier::ZoomRegion::getMagFactor | ( | out float | magX, | |
out float | magY | |||
) |
Get the current x and y magnification ratios.
(Convenience method for getting mag-factor-x and mag-factor-y properties).
magX,: | the magnification factor in the x direction for the specified region. | |
magY,: | the magnification factor in the x direction for the specified region. |
Bonobo::PropertyBag GNOME::Magnifier::ZoomRegion::getProperties | ( | ) |
Gets the current property settings for this ZoomRegion.
Properties managed by the ZoomRegion include "smoothing-type", "contrast", "inverse-video", "border-size", "border-color", "x-alignment", "y-alignment", "is-managed", "viewport", "mag-factor-x", "mag-factor-y".
oneway void GNOME::Magnifier::ZoomRegion::setROI | ( | in RectBounds | bounds | ) |

bounds,: | the ROI bounding box |
void GNOME::Magnifier::ZoomRegion::markDirty | ( | in RectBounds | dirtyRegion | ) |

mouse_x,: | the x screen coordinate of the pointer hotspot | |
mouse_y,: | the y screen coordinate of the pointer hotspot |
void GNOME::Magnifier::ZoomRegion::setContrast | ( | in float | R, | |
